How does this handle Slack's 64KB emoji limit?

The skill includes specialized validators and aggressive optimization techniques like color reduction and frame limiting specifically designed to keep animated emojis under the 64KB threshold.

Is text rendering supported for small GIFs?

Yes, it includes a typography helper that adds outlines to text, ensuring it remains readable even at the small dimensions required for Slack emojis.

Can I combine multiple animation effects?

Yes. The toolkit uses composable primitives, allowing you to layer effects like 'Shake' and 'Bounce' or apply 'Kaleidoscope' filters to any motion path.

What is the difference between Message and Emoji modes?

Message mode targets 480x480 resolution with a 2MB limit, while Emoji mode targets 128x128 with a strict 64KB limit and higher compression.

Do I need external design software like Photoshop?

No, this skill allows you to generate animations programmatically using Python scripts directly within your Claude Code workflow.
